A light source device includes: a substrate; a light-emitting unit matrix including a plurality of light-emitting units disposed in a matrix on the substrate; and a reflective resin disposed in a region, on the substrate, including a region where the light-emitting unit matrix is disposed. The plurality of light-emitting units include a first light-emitting unit and a second light-emitting unit adjacent to each other in a column direction of the light-emitting unit matrix. The reflective resin includes a first reflective portion disposed between the first light-emitting unit and the second light-emitting unit and extending in a direction intersecting the column direction. At least a portion of an upper surface of the first reflective portion protrudes beyond an upper surface of the first light-emitting unit and an upper surface of the second light-emitting unit.

Light source device and light projecting device

A light emitting device including: a light emitting element including a growth substrate and a semiconductor layer located below the growth substrate; a light transmissive member disposed above a top surface of the light emitting element; and a transparent resin bonding the top surface and a bottom surface of the light transmissive member, wherein the bottom surface encompasses the top surface, the transparent resin continuously covers the bottom surface and a side surface of the semiconductor layer. The transparent resin is disposed to cover a covered portion located at a central portion of the semiconductor layer and to expose an exposed portion located at a side edge portion of the semiconductor layer in a direction parallel to the top surface in a side view, and covers the side surface of the semiconductor layer so that at least 20% in length of the semiconductor layer in the direction is covered.

Light emitting device and light emitting module

A semiconductor device includes: a lead frame; a semiconductor element held by the lead frame; a frame body which is formed on the lead frame to surround the semiconductor element, cover a side surface of the lead frame, and expose a bottom surface of the lead frame; and a protective resin filling a region surrounded by the frame body. The lead frame includes an uneven part formed in a section which is part of an upper surface of the lead frame, and is covered with the frame body.

Semiconductor device

A light distribution controller of a light-emitting device includes a first optical member formed of ZnO disposed over an LED interposing a transparent adhesive, and a second optical member which covers the first optical member. The first optical member includes a first concave portion having an opening in a regular hexagon shape whose area gradually increases. In the first concave portion, inner wall surfaces having inclined surfaces, each of whose bases is formed by one side of the hexagon of the opening shape, are formed. Outside of the first optical member, outer wall surfaces each having a trapezoidal shape are formed. The second optical member includes a second concave portion arranged so that light at an annular peak in the light distribution characteristic of the light traveled through the first optical member is totally reflected.

A light-emitting device includes a light-emitting element; and a lens sectioncovering over the light-emitting element. The lens sectionincludes an entrance surface Son which light from the light-emitting elementis incident; an exit surface Sfrom which the light incident on the entrance surface Sis emitted; and an optical axis L extending so as to penetrate the entrance surface Sand the exit surface S. A concave sectionis formed in an area of the exit surface S, which contains the optical axis L, and two flat sectionsare formed so as to face each other across the optical axis L. The exit surface Sdefines an upwardly-protruding curved surface formed between the two flat sections, and the optical axis L is coincidence with a reference optical axis of the light-emitting element
